Bubendorf, Switzerland, Wednesday, May 26, 2021 – CIS Pharma has developed a coating technology to improve the comfort of silicone hydrogel contact lenses. The technology is based upon a block-copolymer technology comprising a hydrophilic and a hydrophobic part. The co-polymer is used for a non-covalent, adhesive interaction with the silicone part of silicone-hydrogel contact lens to form a hydrophilic layer on the contact lens surface
The block-polymer technology is designed to prevent the contact lenses from lipid deposits, leading to longer and more clear vision during the wearing time. The technology was shown to increase the wettability and to reduce the friction, leading to longer wear time.
The coating technology is applied at the end of the manufacturing process, where the silicone contact lenses are heat sterilized. As a result, the technology is applied efficaciously without adding additional steps to the manufacturing process, causing marginal additional costs only.
